My 1.5 year old Dell Studio 15 notebook computer has a battery and I keep it attached to the notebook but 98% of the time I just plug in the power adapter.
Lately when I unplugged the power adapter, the battery was only good for 10 minutes, and a few days ago, when I unplugged the power adapter, the computer simply turned off.
When clicking on the battery icon on Win 7, it says "Plugged in, not charging":
is the battery dead? Or can Windows 7 have any option to not charge the battery?
It is a Dell Studio 15, I wonder if in such case, it looks like it can be a manufacture's defect, would Dell replace the battery? (if there was a recall, then they probably would, i think). The notebook is 1.5 year old.
Answer
Your battery is probably dead, but here are a few things you can try:
- Perform an ATX reset. Remove all power (battery + power lead) and hold the on button down for 30 seconds.
- In
control panel > power management(or the equivalent from XP) turn off the options "shutdown / standby when battery critically low" or similar, so Windows will never try to turn itself off when the battery is low. - Run the battery right down (probably not that difficult :D)
- Leave it plugged in for 16 hours.
- Start her up on battery alone and
see how far you get.
Repeat steps 3, 4 and 5 if you notice your laptop stays alive for longer and longer periods of time as suggested in step 5.
If this isn't successful you have effectively diagnosed a dead battery.
